For the product FLDN3305G, the readings are in STANDARD LPM?
Thank you for your inquiry. The FLDN3305G has a range of up to 120mL/min. The units on the scale will be in mL/min.

Where do I reed the ball on the FLDA3214G-NV flow meter. The top or the center?
Thank you for your inquiry about the rotameters. The Rule of Thumb is to read the flow rate at the highest and widest part of the float and in this case, a sphere will be the center.

Hi. Can I assume that all FLD series meters are volumetric, or is there an option to order them so that they are standardized?
Thank you for your inquiry. They are calibrated at standard conditions, yet, no options for a calibration certificate.

Ordered an FLDA3420C-NV rotameter. Per spec sheet it has a max flow of 10 L/min. But now see the website says the units are SCFM and the readings on the meter go to 10. Which is the correct measurement unit?
Thanks for your question?
The part number, FLDA3420C-NV, rota-meter with no valve has been confirmed to have a max flow capacity of 10 LPM.

Is the connection 1/8 pipe size? or 1/8'' Outer Diameter?
Thank you for your inquiry. The process connection is 1/8 inch NPT

Is there an option available that can be sanitized in place using peroxyacetic acid?
Thank you for your inquiry. If you would like to use the acid in question to clean, please consult a Chemical compatibility handbook to determine if the wetted materials are chemically compatible.

Certificate Traceable to NIST
Thank you for your inquiry for this rotameter. Unfortunately, there is no option for a NIST certificate for this series, you may consider the FL-3600, 3700, 3800, and 3900 series.

How do I read the flow meter / take the reading of FLDA3212ST model? Do I read the float at the top, middle or bottom? The model we got is FLDA3212ST
Thank you for your inquiry about the rotameters. The Rule of Thumb is the highest and widest part of the float.
